The Internet as we know it took 30 years to come to everybody, and it was providing something that essentially wasn't provided before.
Internet2 provides the same thing, only faster; so why do we believe it will replace the existing solution *EVER*, much less in a shorter time frame than 30 years?
The Internet is going to be with us for a very long time. Emphasis should be on fixing it, not replacing it.
Is it just me or is the Internet2 not a very big deal? Its based on OC-48c and OC-192c technology as far as I know, so why would its adoption change _anything_ except the some switch or router gear that guarantees QoS?
I admit my information may be woefully out of date; I saw an article in InternetWeek about transfering a file at 40Mbit/s. I wouldn't see the big deal at 400Mbit/s.
A link to review first: http://www.internet2.edu/news/html/i2lsr.html In any event, Internet-2 is *not* about having a bigger pipe (best left to James Cameron - if size really does matter) - it is about having a smarter pipe. Smartness may manifest itself as: - on paper: QoS end to end - in practice - the ability to view an MPEG-1 2Mb/sec video with no packet loss from 6000 miles away. Try watching any of these at 2+Mb/sec: http://media2.bmrc.berkeley.edu/demo/mpeg/ http://www.researchchannel.com/ondemand/duke/HalfTimePromo.html http://www.researchchannel.com/ondemand/duke/Asx/ht_spot_m2_56m.asx It doesn't matter how fat a pipe you have - it depends how loaded it may be. Let me know how well you see it. I see it is fine - each and every time - over a mere T3. - on paper: going at 800Mb/sec end to end - in practice: how many TCP tuned systems do you know out there that can handle 800Mb/sec? I'll make it easier - how many systems that can handle 10Mb/sec TCP streams (sending) from coast to coast? Try: http://www.psc.edu/networking/perf_tune.html - in practice: ADSL users suddenly got huge performance boosts when they realized they needed to tune their Windows TCP stack. I consider that a trickle down affect of I2 research, already. -Hank
